Examination of poverty trajectories and brain volume as predictors of adolescent depression
Adolescence is a sensitive period during which socioeconomic conditions can shape brain development and mental health. To further clarify such pathways, the present study examined how trajectories of different poverty indices across adolescence relate to brain structure and depressive symptomatology. In a sample of 206 Mexican‐origin youth, latent growth curve modeling was used to assess parent‐reported income‐to‐needs and economic hardship measu…
Within‐person longitudinal associations between depressive symptoms and interpersonal problems in adolescent girls
BACKGROUND: Adolescence, particularly for girls, is a period of heightened risk for depressive symptoms and increased interpersonal stress. Although depressive symptoms and interpersonal problems are known to co-occur, prior work has predominantly examined between-person associations, leaving within-person processes unclear. This study addressed this gap by testing longitudinal within-person associations between depressive symptoms and interperso…
Economic, socio-emotional, and food security conditions during Covid-19 pandemic among caregivers of young adolescents aged 10–12 yrs in a semi-urban setting in Ghana
Few studies have described the consequences of the COVID − 19 pandemic among caregivers of young adolescents in sub-Saharan Africa. We aimed to explore the consequences of COVID-19 on economic, socio-emotional, and household food security conditions among caregivers of young adolescents in a semi-urban setting in the Eastern Region of Ghana. In this cross-sectional study, caregivers of young adolescents aged 10-12yrs in the Somanya-Kpong area wer…
Identifying patterns and predictors of social health in adolescence using data from the Adolescent Brain Cognitive Development Study
Social health, having an adequate quantity and quality of social relationships, is essential for well-being but understudied during adolescence compared to adulthood. We sought to identify patterns and predictors of social health by characterizing peer relationships among 10,050 adolescents (10-13 years old, 4,815 girls, 53.68% non-Hispanic White) in Year 2 of the Adolescent Brain Cognitive Development Study. To characterize social health profile…
Implicit peer versus maternal influence on adolescents’ preferences
Adolescence is a formative time for identity development. A key component of identity development involves weighing the explicit opinions of close others when forming one's preferences. Little is known about how more subtle forms of social input may influence adolescents' formation of their own preferences. In the present study, we used a novel social influence paradigm to assess shifts in adolescents' preferences after viewing implicitly deliver…
Warm Parenting Throughout Adolescence Predicts Basal Parasympathetic Activity Among Mexican‐Origin Youths
Parenting that is warm and supportive has been consistently linked to better emotion regulation in children, but less is known about this association in adolescents. Adolescence is thought to be an important period for emotion regulation development given that it coincides with the emergence of mental health issues. Respiratory sinus arrhythmia (RSA) is a measure of parasympathetic regulation linked to emotion and behavior regulation. Despite the…
Understanding the paradox
Anhedonia is a symptom encompassing reduced or absence of motivation and pleasure that often emerges in adolescence and conveys risk for different mental illnesses and other difficulties. In their review, Gupta, Eckstrand, and Forbes ( Journal of Child Psychology and Psychiatry , 2024) present an empirically‐based conceptual neurodevelopmental model of anhedonia whereby brain development and pubertal maturation create openness to vulnerability to…
Effect of Early‐Life Lipid‐Based Nutrient Supplement and Home Environment on Autonomic Nervous System Regulation at 9–11 Years
Nutrition and the home environment contribute to the development of the autonomic nervous system (ANS). However, no study has examined the long-term effects of prenatal and postnatal small-quantity lipid-based nutrient supplements (SQ-LNS) and home environment on ANS regulation. We investigated the effect of early-life SQ-LNS and home environment on ANS regulation at 9-11 years. Participants were children born to women who participated in a rando…
Parasympathetic regulation and support from family and friends predict prosocial development in U.S. Mexican-origin adolescents
Both parasympathetic nervous system regulation and receipt of social support from close relationships contribute to prosocial development, although few studies have examined their combined influences in adolescence and particularly within racially and ethnically minoritized populations. In this longitudinal study of 229 U.S. Mexican-origin adolescents (48% female-identifying), youths reported on receipt of social support from family and friends f…
Ethnic pride and cultural values promote positive youth development in a conceptual replication of the Five Cs model
The current study examined the Five Cs model of positive youth development (PYD; Lerner et al., 2005) in U.S. Mexican-origin youth ( N = 674, 50% female) and tested the extent to which ethnic pride, familismo, and respeto, as an index of cultural orientation, predicted PYD across midadolescence. PYD was modeled using a bifactor structure, which defined global PYD and the Five Cs (Caring, Character, Competence, Confidence, and Connection) using th…
Prospective associations between emotion regulation and depressive symptoms among Mexican-origin adolescents
Reappraisal (reconstruing emotional experiences to alter their impact) and suppression (inhibiting emotionally expressive behavior) are emotion-regulation strategies with important implications for depression. While reappraisal generally predicts lower depressive symptoms, suppression generally predicts higher depressive symptoms. Because cultural factors can influence the processes involved in these links and because adolescence-especially for e…
Maternal socialization of emotion and the development of emotion regulation in early adolescent girls
Regulation of negative emotions is a core competency of child development. Parental emotion socialization profoundly influences later capacity to regulate negative affect in childhood and adolescence. The present study examined the effects of maternal emotion socialization on the development of emotion regulation in the context of a longitudinal study of 210 mother-daughter dyads. Dyads completed a conflict resolution task when the child was age …
The impact of social disadvantage on autonomic physiology of latinx adolescents
The experience of poverty embodies complex, multidimensional stressors that may adversely affect physiological and psychological domains of functioning. Compounded by racial/ethnic discrimination, the financial aspect of family poverty typically coincides with additional social and physical environmental risks such as pollution exposure, housing burden, elevated neighborhood unemployment, and lower neighborhood education levels. In this study, we…
Cognitive reappraisal and need to belong predict prosociality in Mexican‐origin adolescents
This two-year longitudinal study examined Mexican-origin adolescents' need to belong and cognitive reappraisal as predictors of multiple forms of prosocial behavior (i.e., general, emotional, and public prosocial behaviors). Prosocial behaviors, which are actions intended to benefit others, are hallmarks of social proficiency in adolescence and are influenced by intrapersonal abilities and motivations that typically develop during adolescence. Ye…
Physical and social anhedonia in female adolescents
Anhedonia is a transdiagnostic symptom of psychopathology that includes diminished positive emotions and anticipation and enjoyment of reward, with particular salience during adolescence. However, the construct validity of anhedonia dimensions is not well established, thus limiting operationalization and generalization of the construct. We applied exploratory and confirmatory factor analyses to identify latent dimensions of anhedonia across four …
Research Review
BACKGROUND: Adolescence is a period of high risk for the onset of depression, characterized by variability in symptoms, severity, and course. During adolescence, the neurocircuitry implicated in depression continues to mature, suggesting that it is an important period for intervention. Reflecting the recent emergence of 'precision mental health' - a person-centered approach to identifying, preventing, and treating psychopathology - researchers ha…
Do Hostile School Environments Promote Social Deviance by Shaping Neural Responses to Social Exclusion
The present study examined adolescents' neural responses to social exclusion as a mediator of past exposure to a hostile school environment (HSE) and later social deviance, and whether family connectedness buffered these associations. Participants (166 Mexican-origin adolescents, 54.4% female) reported on their HSE exposure and family connectedness across Grades 9-11. Six months later, neural responses to social exclusion were measured. Finally, …
Developmental Change in Sibling Support and School Commitment Across Adolescence
School commitment typically declines across adolescence, but the family-level factors that explain this decline have not been fully characterized. This study investigated sibling support as a family resource in predicting school commitment across 7th-10th grade using a sample of 444 adolescents (M ages = 12.61, 13.59, 14.59, 15.58 years). Results showed that sibling support linearly increased and school commitment decreased and stabilized, indepe…
Adolescent Externalizing Problems
Models of the etiology of adolescent antisocial behavior suggest that externalizing problems may reflect a susceptibility to crime exposure and a diminished capacity for emotion introspection. In this study, adolescents of Mexican origin completed a neuroimaging task that involved rating their subjective feelings of sadness in response to emotional facial expressions or a nonemotional aspect of each face. At lower levels of neural activity during…
Social re-orientation and brain development
Social development has been the focus of a great deal of neuroscience based research over the past decade. In this review, we focus on providing a framework for understanding how changes in facets of social development may correspond with changes in brain function. We argue that (1) distinct phases of social behavior emerge based on whether the organizing social force is the mother, peer play, peer integration, or romantic intimacy; (2) each phas…
Young Children's Affective Responses to Acceptance and Rejection From Peers
This study presents a novel task examining young children's affective responses to evaluative feedback-specifically, social acceptance and rejection-from peers. We aimed to determine (1) whether young children report their affective responses to hypothetical peer evaluation predictably and consistently, and (2) whether young children's responses to peer evaluation vary as a function of temperamental shyness and gender. Four- to seven-year-old chi…

Age Differences in Home Computer Availability and Use
The lower rates of home computer availability and use exhibited by older persons may be accounted for to some extent by compositional characteristics negatively associated with availability and, to a lesser extent, use of computers, although unmeasured attitudes, experience, and support undoubtedly play a role
